New KT150 tubes?

Has anyone any experience with these pretty new tubes. There are already one or 2 amps I know of, that use them. The review of one of these amps in a UK magazine suggested they were a little warmer and more natural sounding than the nearly new KT120's

The article also suggested they were a straight swap for KT120 based amps, with no adjustment necessary. They are more than twice the cost of KT120's, but still not too costly compared with NOS tubes. I know changing from KT88's or 90's to 120's. did require some amp modification. I have an ARC reference 75 and might want to try the new tubes at some point, ARC don't seem to have a customer E-mail service, to ask the question

if the come anywhere nere the Tesla Vršovice kt88 in sound I will gladly pay $7-800 for an octet. The Eat KT88 which I believe to be the same as the tesla are fetching $1400 for the quad which is crazy money for (most of us . that being said those KT88 had air and space Carnagie Hall compared to local bar) like nothing Ive heard before or since.Too bad they were a bad match for my hard driving rogue 120s.

Has anyone here heard the Eats and the 150s?

Hmmm, standard ARC Central Obfuscation ! I had enough of this when inquiring as to the current situation over ARC's lack of customer disclosure in regard to their phasing out of the 2Uf Teflon coupling capacitors on the Ref 150 .

I sincerely hope that you have not been in any way compromised over this Gary !

Tsushima1, please explain what you meant when you posted that ARC was "phasing out of the 2Uf Teflon coupling capacitors on the Ref 150." I own the Ref 150 so I have a real interest.

Although I barely care what ARC says about most things, I'm tempted to ask them about the 150s simply because I was asked not to.

You should have no concerns as long as you experience no necessity for ARC to replace any of your 2uF coupling capacitors ,note post #17.

(I trust that posting the above does not contravene any forum rules ? , my apologies to the Mod's in advance and please delete should this be the case )
